The technique, tiled M0, leverages the unique structure of tiled Ansa\u0308tze (e.g., tUPS, QNP, and hardware-efficient circuits) to apply a locality approximation to M0 that results in an exponential reduction in the QPU cost of the noise characterization. We validate the technique for molecular ground-state energy calculations with the tUPS Ansatz on LiH, H2, H2O, butadiene, and benzene (4\u201312 qubits), demonstrating little to no loss in accuracy compared to M0 in noisy simulations. We also show the performance of the technique in quantum experiments, highlighting its potential use in near-term applications.<\/jats:p>","DOI":"10.1021\/acs.jctc.6c00603","type":"journal-article","created":{"date-parts":[[2026,8,11]],"date-time":"2026-08-11T14:01:33Z","timestamp":1786456893000},"page":"8188-8200","source":"Crossref","is-referenced-by-count":0,"title":["Cost-Effective\nScalable Quantum Error Mitigation for\nTiled Ansa\u0308tze"],"prefix":"10.1021","volume":"22","author":[{"ORCID":"https:\/\/orcid.org\/0009-0000-6406-3789","authenticated-orcid":true,"given":"Oskar","family":"Graulund Lentz Rasmussen","sequence":"first","affiliation":[{"name":"University of Southern Denmark , , Campusvej 55 , M,","place":["Odense, Denmark, DK-5230"]}],"role":[{"vocabulary":"crossref","role":"author"}]},{"ORCID":"https:\/\/orcid.org\/0000-0002-8489-3496","authenticated-orcid":true,"given":"Erik","family":"Kjellgren","sequence":"additional","affiliation":[{"name":"University of Southern Denmark , , Campusvej 55 , M,","place":["Odense, Denmark, DK-5230"]}],"role":[{"vocabulary":"crossref","role":"author"}]},{"ORCID":"https:\/\/orcid.org\/0000-0003-2406-700X","authenticated-orcid":true,"given":"Peter","family":"Reinholdt","sequence":"additional","affiliation":[{"name":"University of Southern Denmark , , Campusvej 55 , M,","place":["Odense, Denmark, DK-5230"]}],"role":[{"vocabulary":"crossref","role":"author"}]},{"ORCID":"https:\/\/orcid.org\/0000-0003-4812-0522","authenticated-orcid":true,"given":"Stephan P.
